Hi, there,
 I have create a simple project of kotlin/javascript. the code is following
open class Person(open val name: String) { } class Student(override val name:String):Person(name) { } obviously, the Student class inherit from Person.
 The main function is like that
fun main(args: Array<String>) { val person = Person("bbb") print(person.name) } then I debug in browser, the code run down
the program can not find the name property, So I check the js file what the kotlin generate. Then I have found that the some property name in both base class Person and derived class Student are compile to different variables. name  and another is include some suffix like name_w3f4vz$_0.
 the js file is as following:
if (typeof kotlin === 'undefined') { throw new Error("Error loading module 'KotlinJavaScriptTest'. Its dependency 'kotlin' was not found. Please, check whether 'kotlin' is loaded prior to 'KotlinJavaScriptTest'."); } var KotlinJavaScriptTest = function (_, Kotlin) { 'use strict'; var print = Kotlin.kotlin.io.print_s8jyv4$; var println = Kotlin.kotlin.io.println_s8jyv4$; Student.prototype = Object.create(Person.prototype); Student.prototype.constructor = Student; function main(args) { var person = new Person('bbb'); print(person.name); } function Person(name) { this.name_gb5y79$_0 = name; } Object.defineProperty(Person.prototype, 'name', { get: function () { return this.name_gb5y79$_0; } }); Person.$metadata$ = { kind: Kotlin.Kind.CLASS, simpleName: 'Person', interfaces: [] }; function Student(name) { Person.call(this, name); this.name_w3f4vz$_0 = name; } Object.defineProperty(Student.prototype, 'name', { get: function () { return this.name_w3f4vz$_0; } }); Student.prototype.printSuperProperty = function () { println(Kotlin.callGetter(this, Person.prototype, 'name')); }; Student.$metadata$ = { kind: Kotlin.Kind.CLASS, simpleName: 'Student', interfaces: [Person] }; _.main_kand9s$ = main; _.Person = Person; _.Student = Student; main([]); Kotlin.defineModule('KotlinJavaScriptTest', _); return _; }(typeof KotlinJavaScriptTest === 'undefined' ? {} : KotlinJavaScriptTest, kotlin); //# sourceMappingURL=KotlinJavaScriptTest.js.map So How can I solve this problem, Thank you!!!
